The amount of memory required for each compressed block is printer
specific. The QMS 2060 Print System takes approximately 64 KB of
memory from the display list for each compressed block. However, if a
page includes raster image data (for example, TIFF or bitmap data),
each compressed block will require much more memory.
Increasing the amount of memory in this client may improve printing
throughput and minimize slowdowns due to collating or printing com-
plex pages. If your QMS 2060 Print System has a hard drive and the
disk swap option is enabled the memory added to this client is taken
from virtual memory. If your printer does not have a hard disk then the
memory added to this client is taken from the amount of physical
memory in your printer. It may be necessary to reduce memory added
to another client before adding memory to the Display List. Check that
the Frame Buffer still has the minimum amount of memory needed for
your printing needs before reallocating this memory.

Also known as K Mem PS Fonts and Font Cache, this memory client
stores bitmapped representations of previously scaled PostScript
fonts. This process reduces the number of times a font must be con-
verted from outline form to bitmap form. Printing pages that have
characters already stored in the font cache is immensely faster than
printing characters not yet in the font cache.
As the font cache memory fills, the printer makes room for new bit-
mapped characters by erasing those that have been in the cache
longest without being used. By increasing the memory allocated to
this client, the printer can store more characters and spend less time
erasing and replacing characters in the cache. You should be careful
when increasing this client because the printer may spend more time
searching the cache than it would scaling the character. This client
has a limit to the maximum point size it will store.
Normally, you don’t need to change this memory client unless you
use a large number of fonts at various point sizes. If you do, you may
allocate additional memory to this client to improve printer perfor-
mance.
